    Measurements with the Push of a ButtonAs the circuits in embedded system designs become more sophisticated,you must measure a multitude of different parameters to validate yourdesign. The Tektronix DMM4020 5.5 digit bench multimeter offers a broadrange of functions in one easy-to-use instrument.Typical multimeter measurements volts, ohms, and amps are made witha basic VDC accuracy of up to 0.015%, ensuring you have the performanceyou need for your design. You can also use the DMM4020 to measurefrequency, and to perform continuity and diode tests. This allows youto replace your counter, continuity tester, and DMM with one versatileinstrument, saving bench space and cost.

    Measure Nanoampere SignalsMeasuring standby current in todays energy-efficient designs requireslooking at very low currents, often in the microamp or nanoamp range.Using a traditional multimeter for this measurement can lead to inaccurateresults since they typically employ the shunt resistance technique formeasuring current.The DMM4020 offers an improved method for measuring low currents. Byusing a current-to-voltage op amp technique, the DMM4020 can makecurrent measurements with 1 nA of resolution and with minimal loadingaffect on the circuit under test, giving results that reflect real-world operationof the device.

    Designed to Make YourWork EasierThe DMM4020 multimeter is designed with the ease of use and familiaroperation you expect from Tektronix.

    Intuitive OperationDedicated front-panel buttons provide fast access to frequently usedfunctions and parameters, reducing setup time. You no longer need tosearch through software menus to find the function you need.

    Limit compare mode on the DMM4020.

    Setup Buttons for Your CommonMeasurementsWith six setup buttons on the front panel, you can save the settings for yourmost common measurements. Simply set up the meter for a measurement,then press shift followed by a setup button to save the measurementsettings. Now each time you perform that measurement, you simply pressthe appropriate setup key.

    Dual DisplayWith the unique dual display, you can measure two different parameters ofthe same signal from one test connection.

    Limit CompareThe limit compare mode provides pass/fail indicators to quickly show if atest passes or fails to help eliminate mistakes, especially for results thatare close to the limit.

    Simple and Accurate 4-wire MeasurementsPatented split terminal jacks for the 24 ohms function allow you to perform4-wire measurements using only two leads instead of four. Special test leadaccessories are available to enable you to establish the connection. You getexcellent resolution and accuracy plus the convenience and ease of using asingle pair of leads.

    Easy Connectivity to Your PCThe RS-232 port on the back panel can be used to connect to your PC.A USB to RS-232 interface adapter cable is included standard with theDMM4020 for connecting to your PCs USB port.
